Combining ability of maize inbred lines resistant to Chilo partellus (Swinhoe) in the mid-altitude environment of Kenya
Gene action conditioning important traits in maize is useful to breeders in order to design appropriate breeding methods. A study was conducted to determine the combining ability of 10 maize inbred lines adapted to Kenya?s ...
Winter wheat genotypes under different levels of nitrogen and water stress: Changes in grain protein compositionQuantification of Bt Delta-endotoxins in leaf tissues of tropical Bt maize populations
Hard white winter wheat with superior and consistent quality is preferable for Asian markets. This study investigated the combined influences of moisture deficit during grain-fill and N management on protein quality, dough ...
Yield stability of stem borer resistant maize hybrids evaluated in regional trials in east Africa
Twenty-seven stem borer-resistant maize hybrids and three checks were evaluated in 14 locations in Kenya and Ethiopia to study the genotype x environment interaction (GEI) and yield stability. An analysis of variance was ...
Evaluation of stem borer resistance management strategies for Bt maize in Kenya based on alternative host refugia
Stem borers are the major insect pests of maize in Kenya. The use of Bacillus thuringiensis (Bt) technology is an effective way of controlling lepidopteran pests. However, the likelihood of development of resistance to ...
Genotype by environment interactions and yield stability of stem borer resistant maize hybrids in Kenya
In a maize breeding program, potential genotypes are usually evaluated in different environments before desirable ones are selected. Genotype x environment (G x E) interaction is associated with the differential performance ...
Molecular characterization of diverse CIMMYT maize inbred lines from eastern and southern Africa using single nucleotide polymorphic markers
(BioMed Central, 2012)
Knowledge of germplasm diversity and relationships among elite breeding materials is fundamentally important in crop improvement. We genotyped 450 maize inbred lines developed and/or widely used by CIMMYT breeding programs ...
Grain yield, stem borer and disease resistance of new maize hybrids in Kenya
Evaluation of 30 maize hybrids for yield and resistance to stem borers and foliar diseases in four agro-ecologies in Kenya was conducted in 2009. There were significant differences among the hybrids in leaf damage, number ...
